PART 2 - LOW VOLTAGE DRAWOUT SWITCHGEAR

A. Breaker and Instrument Compartments.

Periodic inspection of the circuit breaker is recommended at least once a year. More frequent inspections are recommended where severe load conditions, dust, moisture or other unfavorable conditions exist, or if the vital nature of the load warrants it. Always inspect the breaker after a short-circuit current has been interrupted

Breakers – Test for proper operation: Test and inspect all circuit breakers for proper operation as follows:

a. Operate each breaker while in the TEST position and check all functions. This is particularly important for breakers that normally remain in either the opened or closed positions for long periods of time.

WARNING: Primary equipment must be completely de-energized while tests on control circuits, etc. are being conducted. Be sure that all areas of feedback from secondary circuits, as well as outside sources, are disconnected.

b. Remove the breakers from their compartments to a clean maintenance area. Close compartment door and cover the breaker cutout to prevent access to live parts.

WARNING: De-energize equipment completely before doing maintenance work on any devices, connection, bus work, breaker, or feeder cable compartments. This


2

includes de-energizing any connections to outside primary or secondary sources, such as transformers, tie lines, etc.

B. Checks After Breaker is De-energized.

At the time of inspection, the following checks should be made after the breaker has been de-energized:

Manually operate the breaker several times, checking for obstructions or excessive friction. Manual closing of an electronically operated breaker may be performed by the following steps:

a. To charge the mechanism springs, pull the operating handle down until it stops (about 900) ten times for the EntelliGuard breaker. The charge indicator will show CHARGED on a yellow background.

b. Depress the CLOSE button on the front of the breaker. The springs should discharge and, if the latch is properly reset, the breaker will close.

Electrically operate the breaker several times to check performance of the electrical accessories.

Visually check the breaker for loose hardware on the breaker; also, check the bottom of the compartment for any hardware that has fallen from the breaker.

Remove and inspect the arc quenchers and contacts for breakage or excessive burning.

The performance of the solid-state current trip devices may be checked with a suitable

test set. Check electro-mechanical devices for positive trip in accordance with the instructions in the proper Maintenance Manuel.

Check insulating parts for evidence of overheating and for cracks that indicate excessive

thermal aging.

Lubrication: In general, the circuit breaker requires moderate lubrication. Bearing points and sliding surfaces should be lubricated at the regular inspection periods with a thin film of manufacturer approved lubricant. Before lubricating, remove any hardened grease and dirt from the latch and bearing surfaces with mineral spirits then wipe with a clean rag.

CAUTION: All excess lubricant should be removed with a clean cloth to avoid accumulation of dirt or dust.

On draw-out breakers, the contact surface of the disconnect fingers should be cleaned

and greased with manufacturer approved lubricant.

C. Instruments, Instrument Transformers, and Relays

Check and inspect all devices to see that they are functioning properly. Check that all electrical connections are tight. Check mounting of the device.

Under normal conditions, the protective relays do not operate; therefore, it is important to check the operation of these devices regularly. Refer to Relay Instruction Books for detailed instruction.

Breaker Compartment Interiors

WARNING: De-energize equipment completely before doing maintenance work in compartments. This includes de-energizing any connections to outside primary or secondary sources, such as transformers, tie lines, etc.

Thoroughly clean the interior of the breaker and instrument compartments. Use a vacuum cleaner and clean rags only. Do not use steel wool or oxide papers. Blowing with compressed air is not recommended.

Check indicating devices, mechanical and key interlocks.

Check primary disconnecting device contacts for signs of abnormal wear or overheating. Discoloration of the silvered surfaces is not ordinarily harmful. These contacts should be cleaned only by wiping with a lint-free cloth.

Clean the racking mechanism and lubricate with manufacturer approved lubricant.

Before replacing the breaker, wipe off the primary disconnecting device contacts. Apply

a thin coat of manufacturer approved lubricant to the stationary studs and to the primary disconnects on the breaker.

D. Bus Area

WARNING: De-energize equipment completely before doing maintenance work on any devices, connections, bus work, breaker or feeder cable compartments. This includes de-energizing any connections to outside primary or secondary sources, such as transformers, tie lines, etc.

Inspect the buses and connections carefully for evidence of overheating or weakening of the insulating supports. If bus insulation is present, remove the molded covers over the main bus connection to expose joints for inspection.

Check all connection bolts in the bus compartment and all bracing bolts for tightness.

Vacuum and, with a clean rag, wipe the buses and supports.

Visually inspect the insulation on the bars that run from the breaker studs through the bus structure to the cable area.

After cleaning, megger and record the resistance to ground and between phases of all

insulated bars and all buses and connections. Disconnect all control circuits before checking resistance. Do not use over a 1500-volt megger. Since definite limits cannot be given for satisfactory insulation resistance values, a record must be kept of the readings.

E. Cable and Busway Compartment Inspect and check the cable and busway compartment as follows:

Inspect all power cable connections for signs of overheating and tighten all connections. If severe discoloration or if damage is apparent, remove the damaged portion of the cable.

CAUTION: Be sure the condition which caused the over-heating has been corrected before energizing.


4

Check all bolts that hold cable terminals to the connection bars for tightness.

Check the neutral bus and ground bus connection and mounting bolts for tightness.

Check that all secondary control wiring connections are tight and that all control cabling is

intact.

F. Overall Switchgear

Make the following checks on the complete switchgear equipment.

Clean and inspect all painted surfaces and retouch where necessary.

Check to see that all anchor bolts and other structural bolts are tight.

Check that all breaker and instrument compartment door latches operate properly.

If the switchgear is equipped with heaters, check to see that all heaters are energized and operating.

For exterior vent opening in equipment furnished with air filters, the foam filter elements

should be removed and washed in warm soapy water, rinsed and reassembled at least annually. Elements should be inspected before re-assembly and replaced if any signs of deterioration are evident.

G. Circuit Breaker Lifting Mechanism

Under normal conditions, no special maintenance procedures or lubrication is required for this device. If the cable is abraided under any condition, it should be inspected for broken strands or other damage and replaced if necessary.

H. Torque all bolted connections to manufacturing specifications.

PART 3 - SWITCHBOARDS

A. Bus Compartment


Inspect and check the bus area as follows:

Inspect the buses and connections carefully for evidence of overheating or weakening of the insulating supports.

Check all connection bolts in the bus compartment and all bracing bolts for tightness.

Vacuum and, with a clean rag, wipe the busses and supports.


5

Visually inspect the insulation on the bars that run from the breaker studs through the bus

structure to the cable area.

After cleaning, megger and record the resistance to the ground and between phases of all insulated bars and all buses and connections. Disconnect all control circuits before checking resistance. Do not use over a 1500-volt megger. Since definite limits cannot be given for satisfactory insulation resistance values, a record must be kept in the readings.

Weakening of the insulation from one maintenance period to the next can be recognized from the recorded readings. The readings should be taken under similar conditions each time, if possible, and the record should include the ambient temperature and humidity.

B. Cable Compartment

Inspect and check the cable and busway compartment as follows:

Inspect all power cable connections for signs of overheating and tighten all connections. If severe discoloration or if damage is apparent, remove the damaged portion of the cable.

CAUTION: Be sure the condition which caused the overheating has been corrected before energizing.

Check all bolts that hold cable terminals to the connection bars for tightness.

Check the neutral bus and ground bus connection and mounting bolts for tightness.

Check that all secondary control wiring connections are tight and that all control cabling is

intact.

C. Breaker and Switch Compartment


Inspect and check the device compartments as follows:

Thoroughly clean the interior of the breaker and instrument compartments. Use vacuum

clean rags only. Do not use steel wool or oxide papers. Blowing with compressed air is not recommended.

Check indicating devices, mechanical and key interlocks.

Check primary disconnecting device contacts on drawout devices for signs of abnormal wear or overheating. Discoloration of the silvered surfaces is not ordinarily harmful. These contacts should be cleaned only by wiping with a lint-free cloth.

Clean the racking mechanism and lubricate with manufacturer approved lubricant.


6

Before replacing the drawout breaker, wipe off the primary disconnect contacts. Apply a thin coat of manufacturer approved lubricant to the equipment stabs and to the primary disconnect fingers on the breaker.

Operate each drawout breaker while in the TEST position to be sure it functions properly.

This is particularly important for breakers that normally remain in either the opened or closed positions for long periods of time.

D. Metering and Control Devices

1. Check and inspect all devices to see that they are functioning properly. Check that all electrical connections are tight. Check mounting of the device. Under normal conditions, the protective relays do not operate; therefore, it is important to check the operation of these devices regularly.

E. Overall Equipment

Make the following checks on the complete switchgear equipment:

Clean and inspect all painted surfaces and retouch where necessary.

Check to see that all anchor bolts and other structural bolts are tight.

Check that all breaker and instrument compartment door latches operate properly.

If the switchboard is equipped with heaters, check to see that all heaters are energized and operating.

For exterior vent opening in equipment furnished with air filters, the foam filter elements

should be removed and washed in warm soapy water, rinsed, and reassembled at least annually. Elements should be inspected before reassembly and replaced if any signs of deterioration are evident.

F. Breaker Lifting mechanism (Hoist)

Under normal conditions, no special maintenance procedures or lubrication is required for this device. If the cable is abraided under any condition, it should be inspected for broken strands or other damage and replaced if necessary.

G. Ambient Temperatures and Circuit Loading

Switchboards are designed for installation where average ambient temperature will not exceed 40 degrees Celsius (104 degrees Fahrenheit). For higher temperatures, derating may be required. The conductor temperatures within the enclosure may be as high as 105 degrees C (220 Degrees F). Some parts of breakers, switches, and fuses may run hotter. Refer to the NEMA or UL standards for those devices and for switchboards for their maximum allowable or anticipated temperature rises above ambient.


7

H. Short Circuits

Normally, the overcurrent protective device on the circuit will prevent any electrical damage except at the actual point of short-circuit. A thorough inspection of the entire system after any fault current should be made to ensure that there has been no mechanical damage to the conductors, insulation or equipment.

In addition, the individual overcurrent protective device or devices which performed the short-circuit interruption MUST be inspected for possible arcing damage to contacts, arc chutes and/or insulation. Do not open sealed devices such as breaker trip units. If there is any possibility that sealed units may have been damaged, they should be replaced.

I. Arcing damage kk

Some organic insulating materials carbonize when subjected to the heat of an electrical arc and lose their insulating qualities. Any insulation found to be carbon tracked must be replaced before applying power.

J. Bolt torque for electrical joints

Torque all bolted connections per manufacturer’s specification.

PART 4 - PANELBOARDS

A. Accumulation of Dust and Dirt:

If there is an accumulation of dust and dirt, clean out the panelboard by using a brush, vacuum cleaner, or clean lint-free rags. Avoid blowing dust into circuit breakers or other components. Do not use a blower or compressed air.

1. Carefully inspect all visible electrical joints and terminals in the bus and wiring system.

2. Visually check all conductors and connections to be certain that they are clean and

secure. Loose and/or contaminated connections increase electrical resistance which can cause overheating. Such overheating is indicated by discoloration or flaking of insulated and/or metal parts. Pitting or melting of connecting surfaces is a sign of arcing due to a loose or otherwise poor connection. Parts which show evidence of overheating or looseness should be cleaned and re-torqued or replaced if damaged. Tighten bolts and nuts at bus joints to manufacturer’s torque specification.

B. Proper Ampere, Voltage , And Interrupting Ratings

1. Check circuit breakers, switches and fuses to ensure they have the proper ampere, voltage and interrupting ratings. Ensure that non-current-limiting devices are not used as replacements for current-limiting devices. Never attempt to defeat rejection mechanisms which are provided to prevent the installation of the incorrect class of fuse.


8

C. Mechanisms Free and In Proper Working Order

1. Operate each switch or circuit breaker several times to ensure that all mechanisms are free and in proper working order. Replace as required. See NEMA-AB-4 for maintenance of molded case circuit breakers.

D. Operation of All Mechanical Components

1. Exercise switch operating mechanisms and external operators for circuit breakers to determine that they operate freely to their full on and off positions.

2. Check the integrity of all electrical and mechanical interlocks and padlocking mechanisms. For key interlocked systems, ensure that only the required numbers of keys are accessible to the operator.

3. Whenever practical, check all devices for missing or broken parts, proper spring tension, free movement, corrosion, dirt, and excessive wear.

4. Adjust, clean and lubricate or replace parts according to the manufacturer’s instructions.

5. Use clean nonmetallic light grease or oil as instructed.

6. Do not oil or grease parts of molded case circuit breakers.

7. If no instructions are given on the devices, sliding copper contacts, operating mechanisms, and interlocks may be lubricated with clean, light grease.

8. Wipe off excess lubrication to avoid contamination.

CAUTION: Hydrocarbon spray propellants and hydrocarbon based sprays or compounds will cause degradation of certain plastics. Contact the panelboard manufacturer before using these products to clean, dry, or lubricate panelboard components during installation or maintenance.

9. Clean and dress readily accessible copper electrical contacts, blades and jaws according to the manufacturer’s instructions when inspection indicates the need.

E. Damaged Insulating Material and Assemblies

Look for and replace damaged insulating material and assemblies where sealing compounds have deteriorated.

F. Moisture or signs of previous wetness or dripping

Look for any moisture or signs of previous wetness or dripping inside the cabinet.

NOTE: Condensation in conduits or dripping from outside sources is one known cause of panelboard malfunction.

1. Seal off any conduits which have dripped condensate and provide means for further condensate to drain away from the panelboard.

2. Seal off any cracks or openings which have allowed moisture to enter the enclosure. Eliminate the source of any dripping on the enclosure and any other source of moisture.


9

3. Replace or thoroughly dry and clean any insulating material, which is damp or wet or shows an accumulation of deposited material from previous wettings.

4. Inspect all component devices. Replace any component device which shows evidence of moisture damage or has been subjected to water damage or flooding. Additional information may be found in the NEMA document “Guidelines For Handling Water Damaged Electrical Products”

G. Before Cleanup and Corrective Action Is Attempted

In the event of water damage, e.g., flooding or sprinkler discharge, the manufacturer should be consulted before cleanup and corrective action is attempted.

H. Severe Electrical Short Circuit

If a severe electrical short circuit has occurred, the excessive currents may have resulted in structural component and/or bus and conductor damage due to mechanical distortion, thermal damage, metal deposits, or smoke. Examine all devices and bus supports for cracks or breakage. The manufacturer should be consulted before cleanup and correction is attempted.

I. Ground Fault Protection System

Test the ground fault protection system (if furnished) in accordance with the manufacturer’s instructions. See Section 230.95 of the National Electrical Code and NEMA PB 2.2 Application Guide for Ground Fault Protective Devices for Equipment.

SEQUENCE OF OPERATION FOR PSE

A. NORMAL/ EMERGENCY

1. UNDER NORMAL CONDITIONS, THE NORMAL POWER FEEDER PROVIDES POWER TO THE LOADS VIA NORMALLY CLOSED MAIN BREAKER INSWITCHGEAR PSE.

2. ON A LOSS OF NORMAL POWER, GEN 1, 2, & 3 WILL START AND THE MAIN NORMAL POWER BREAKER WILL OPEN AND BUS TIE BREAKER WILL CLOSE. THE FIRST GENERATOR TO REACH RATED VOLTAGE AND FREQUENCY WILL RESULT IN THE MAIN GENERATOR BREAKER IN PSE CLOSING INTO THE BUS AND SERVING ALL LOADS SHOWN WHICH ARE PRIORITY 1 LOADS. THE PRIORITY 2 LOAD IS THE DATA CENTER WHICH IS SERVED FROM A 480V BREAKER IN SWITCHGEAR USHXB. ON A LOSS OF POWER THIS BREAKER SHALL BE OPENED AND CLOSED AFTER THE SECOND GENERATOR COMES ONLINE. SEE KEYED NOTE 6 ON E027. THE SECOND AND THIRD GENERATOR WILL CLOSE INTO THE PSE BUS AS THEY ARE SYNCHRONIZED WITH THE FIRST GENERATOR.

3. WHEN NORMAL POWER RETURNS, AFTER A 5 MINUTE DELAY, THE TIEBREAKER WILL OPEN AND THE MAIN NORMAL BREAKER WILL CLOSE.THE LOAD WILL NOW BE SERVED FROM THE NORMAL SOURCE. AFTERA COOLDOWN PERIOD THE GENERATORS WILL SHUTDOWN.

B. LOAD BANK OPERATION

1. THE LOAD BANK ALLOWS TESTING OF ONE GENERATOR AT A TIME.UNDER NORMAL CONDITIONS, THE TIE BREAKER IS OPEN, ISOLATINGTHE NORMAL POWER SOURCE FROM THE EMERGENCY SOURCE.THIS ALLOWS FOR GENERATOR TESTING VIA THE LOAD BANK.

2. SHOULD NORMAL POWER FAIL WHEN THE LOAD BANK IS IN OPERATION,THE MASTER CONTROLLER SHALL IMMEDIATELY SHUTDOWN THE LOADBANK AND BEGIN THE SEQUENCE NOTED ABOVE.
